Edmonton's high pitched annoying horn (there's more, but Edmonton sticks out at the moment)

Phoenix Coyote horn

Boston Wooo

Mostly I just hate high pitched loud noises like all of those. They grate on my nerves and just give me a headache. I don't necessarily think any team should stop any of those things (as long as their own fans like it), but I hate them.

And of course anyone who isn't a Hawks fan hates Chelsea Dagger. It does it's job, but I can't stand it. But actually worse was that song that sounded weirdly similar to Chelsea Dagger that popped up last year that a lot of teams (including the Red Wings, unfortunately) used. Irritated me worse than Chelsea Dagger. I'll try and find the one I'm talking about.

Edit: Locksley's The Whip. Teams tried so hard to make this their own Chelsea Dagger. Like 15 teams used this same song at the same time. It was so frustrating and I was so disappointed to see the Red Wings start using it last year. It just feels like a cheap rip off of Chelsea Dagger.
